Additions and Corrections sample cwettes. Dimethyl sulfoxide had no effect on the binding spectra with addition up to 10% of the final suspension volume. The K, value was determined from a Scatchard plot (absorbance difference vs absorbance difference/concentration = slope K,) and is the average of three determinations (&lo%).
